Application December 15, 1945, Serial No; 635,285

This invention relates to improvements in a rack assembly for refrigerators, ovens and the like.

The main objects of this invention are:

First, to provide a rack assembly for refrigerators, ovens, and the like, which is effectively supported in extended position or when withdrawn from the compartment in which it is mounted to expose the major portion of the surface thereof, and at the same time one which may be easily removed or disengaged from its supports.

Second, to provide a rack structure which is comparatively simple and economical in structure and easily manipulated.

Further objects relating to details and economies of the invention will definitely appear from the description to follow. The invention is defined in the claims.

A structure which embodies the features of the invention is clearly illustrated in the accompanying drawings, in which:

Fig. 1 is a fragmentary view of a structure embodying my invention partially in section on line corresponding to line l--l of Fig. 3, one of the racks being shown in extended position.

Fig; 2 is an enlarged fragmentary perspective view illustrating structural details of the rack supporting rails in relation to a compartment.

Fig. 3 is an enlarged fragmentary view partially in horizontal section on line 3-3 of Fig. 1.

Fig. 4 is an enlarged fragmentary view partially in' horizontal section on line =4-4 of Fig. 1.

Fig. 5 is an enlarged detailed section on line corresponding to line 55 of Fig. 1.

Fig. 6 is a perspective view of a slightly modified form of rack embodying my invention.

Fig. '7 is a fragmentary view showing the rack in proper relation to supporting rails when in its extended position. h

Fig. 8 is a fragmentary view in section on line corresponding to line 88 of Fig. 7.

In the accompanying drawings the cabinet or compartment I is shown mainly in conventional form, this being the lining of an oven or a refrigerator.

I have illustrated only one of the rail units and one side of the rack, as it will be understood that the other rail unit is a duplicate of that illustrated, and that the rack is symmetrical on both sides. The rack assembly is designed to be removably mounted within the compartment although it will. be understood that instead of providing rail assembly units separablefrom the walls of the compartment the rails may be mounted directly upon the compartment walls.

10 Claims. (o1. 211- 143) In the embodiment illustrated I provide. front and rear hanger members 2 and 3 having keyhole slots 4 at their ends, dischargeably engageable with the headed studs 5 projecting inwardly lrfI'OIII the side walls 6 of thecompartment which,

as stated, may be oven walls or refrigerator walls 1 or the like as may be desired. The rails 1 formed of heavy Wire or light rod stock, have laterally turned ends 8 welded or otherwise secured to the hanger 2, see Fig. 5.

The inturned ends 8 at the front of the rails constitute bearing members for the shelf designated generally by the numeral 9.

The shelves or racks 9 comprise side members or bars l0 and a rear member or bar I l and frontmembers at the front ends of the rails, while the cross bars l4 and I5 slidably engage the tops of the rails on which the shelf is supported. The rear ends of the side bars are bent upwardly at 4 I! to support the cross bar I I in an elevated position relative to the plane of the shelf or rack and so that it slidably engages the under side of the rail above and adjacent to the rail upon which the shelf or rack is supported. The rails have downward offsets l8 adjacent their front ends,

these offsets constituting stops coacting with the rear cross bar to limit the outward movement of the racks as they are withdrawn to extended position as illustrated in the lower rack shown in Fig. 1.

The cross bar engaging the under sides of the adjacent upper rail prevents downward tilting of the shelf when it is withdrawn. However, when it is desired to completely remove the shelf or rack, its front end may be tilted upwardly to permit passing of the rear cross bar under the stops.

It will be readily understood that the shelves or racks may be selectively associated with any bars or rails.

In Figs. 6, 7, and 8, the stop offsets 18 are omitted from the rails 1. The offsets l3 of the rack side bar l0 perform thefunction of laterally supporting the rack as the side bars slide upon the bearing portions 8 of the rails but theyalso serve as stops coacting with the bearing memhers 8 which also function as stops. The rear ends of the side bars are upwardly onset at 11 and connected by cross bar I l which rides along under the rails above the rails on which the rack is slidably supported, preventing the rack from tilting downwardly when it is in its extended position or as it is drawn out on the rails.

The rack may be entirely withdrawn by tilting its front end upwardly until the offsets l3will pass the members" 8; and thisis also necessary in the structure shown in Figs. 1 to 5 inclusive, where the offsets [8 in the rails coact with the upwardly onset rear end of the rack to provide stopmeans.- In other words, in the embodiment shown i'n. Fig. 1 there are two stop means, this being,- desir able because the offsets [3 are located ,so closely adjacent to the rear end oiltherack.

I have illustrated and described my invention in an embodiment which is highly satisfactory; I have not attempted to illustrate or describe various modificationsand. adaptations, as. it is believed that this disclosure; will enable those skilled in the artto embody-or adapt-my invention; as maybe desired;
